Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a rotor eccentrically and rotatably supported by a casing, an end wall rotating together with the rotor, and an end wall supported in a slit provided in the radial direction of the end wall and having an end connected to the rotor. a vane extending into a slit in the wall and an actuating chamber between the rotor, the end wall, the vane and the casing portion to accommodate fluid when the volume increases and to discharge fluid when the volume decreases. The present invention relates to a vane machine having vanes and through which a fluid flows.

The gist of the invention is a rotor (rotating piston) and an end wall (rotor end plate) provided in the rotor and rotating with the rotor, the end of which extends into a slit in the wall of the rotor. and between the rotor, the end wall, the blades and the casing section (mantle), the working chamber is flowed through by a fluid which accommodates a fluid, such as a liquid or gas, when the volume increases and releases the fluid when the volume decreases. A fluid sealing element that moves radially within the wing and extends into the tip of the wing in the end wall to allow fluid to flow through the wing chamber - a rotating piston machine - with the wing forming the wing (the wing chamber). The improvement consists in arranging a fluid-tight wing (hereinafter referred to as a fluid-tight edge) in a bed of a fluid-tight edge constructed in the wing and extending into the tip.

Machines having rotors and blades supported in slits in the end walls and having fluid-tight edges therein are described in other patents by the inventors, such as U.S. Pat.
2975716; 3099964; 3269329; Federal Republic of Germany patent specification 1199282; 1292973; Japanese patent specification
225237; 277436; 467020; USSR Patent Specification 292482; DDR Patent Specification 81405 and/or other patents are known and their performance has been confirmed in practice. The machine is characterized by its high fluid tightness. It is likewise known to provide the blades with fluid-tight means or guide them in wing machines which do not have end walls that rotate with the rotor. The machine described below without a rotor end wall is however not as dense as the machine described above with a rotor end wall and a wing bearing in the same wall and is therefore particularly difficult to operate in the low speed range. is not rational. On the other hand, although the machine described above with bearings in the end walls of the co-rotating rotors is advantageously used for speeds of 2 to 3000 rpm, for speeds of 6 to 7000 rpm the centrifugal force of the blades is reduced. This causes high friction between the wing shoe and the mantle. This number is 4000r.
This is especially true at high rotational speeds above pm.
Significant at around 10000rpm.

The object of the invention is therefore to provide a system which is not only economical for a given rotational speed range, as in conventional machines, but also economical for a much wider rotational speed range, especially in the slow and fast ranges. A further object of the invention is to avoid the difficulties experienced by professionals who have heretofore been unable to create machines that are fluid-tight and economical over a very wide range of rotational speeds.

Experts have always experienced the drawbacks of conventional wing machines: insufficient fluid tightness, especially at low rotational speeds, resulting in low volumetric efficiency; Since the practical problems of the instrument are distorted, many documents, for example, very recently, i.e. on November 18, 1969, Endovuen University of Technology, Netherlands -
The paper “Theory and measurement of special problems of hydrostatic vane pumps” published in Technische Hochschule, Eindhoven “Theorien und Messungen zu
Charakteristischen Problemen der
Too many wrong conclusions have been reached regarding the winglet machinery, as shown in ``Hydrostatischen Fl¨ugel-pumpen.'' In fact, this constantly repeated mistake of experts is understandable: leakage occurs. The particles are so small that they are difficult to discern with the human eye.The problem of fluid tightness in wing compartment machines is, on the one hand, due to the axial direction of the working chamber, as described in the original patent. While there is a fluid tightness at the edges, there is also a fluid tightness at the outer corner between the end of the working chamber and the inner surface of the casing part. The effects of mechanical leakage and mechanical efficiency on mechanical efficiency have remained unresolved and even less fully appreciated by the profession to date.

By means of the invention, the above-mentioned drawbacks are overcome. That is, guide means are provided for the radial position of the blades so that the blades are always spaced from the inner surface of the casing part within the required tolerance, and furthermore, according to the invention, a A receiving groove into the wing extending into the slit (hereinafter referred to as fluid-tight edge floor)
is disposed in such a way that it extends into the blade tip of the rotor wall, and within this fluid-tight bed, the present invention extends beyond its length, i.e., the length of the piston boss, into the rotor wall. The fluid-tight edge bed has such a length that it extends to the wing tip and partially touches the inner surface of the casing part at its outer corner, but on the other hand rests on the surface portion of the fluid-tight edge floor in both wing tips. A fluid-tight edge (piston slide-fluid chamber wing) moving inside is arranged. This achieves complete fluid tightness of the corners of the working chamber between the blades, the inner surface of the casing part and the end of the working chamber or end wall of the rotor.

In yet another embodiment of the invention, the floor of the fluid-tight rim is provided with a groove for communicating with an adjacent working chamber, and the fluid-tight rim is adapted to suit the pressure relationship in the adjacent working chamber. is pressed against the inner surface of the casing part.
In yet another embodiment of the invention, a multi-part wing is provided, with several fluid-tight edges within the wing and within the same floor. A radially moving fluid-tight edge is provided, while each bed of the fluid-tight edge communicates with a working chamber different from that adjacent to the wing, so that each of the fluid-tight edges has access to the adjacent working chamber. The pressure in one of the adjacent working chambers is applied while the other fluid tight edge in the same wing is subjected to the pressure in the other working chamber.

A special fluid-tightness, which simultaneously reduces the friction between the fluid-tight edge and the inner surface of the casing part, is achieved in accordance with the invention as follows: the fluid-tight edge with straight corners throughout is provided with a coplanar bearing. The rectilinear corner constituted between the surface and the outer surface bounds the space formed by the fluid-tight edge and the working chamber, and the wall of the fluid-tight bed inside the part of the casing and the tip. This is achieved by being disposed in fluid-tight contact with. The described configuration and contact of the fluid-tight corner creates a fluid-tightness, while the formation of the space provides for radial cleaning of the fluid-tight edge, thus avoiding it being pressed too tightly against the inner surface of the casing. be done.

A machine constructed according to the invention is used as a hydraulic pump for normal and high speeds of internal combustion machines or gas turbines. Furthermore, it is fluid-tight for high-speed hydraulic motors and low-speed rotors, and achieves high fluid-tightness and high rotational speeds as compressors, gas motors, air motors, and internal combustion machines, while at the same time being very good at low speeds. Achieves excellent fluid tightness.

The invention will now be described in detail with reference to the accompanying drawings relating to embodiments.

FIGS. 1 and 2 show known features of the casing of a known wing machine, in which the shaft 12 and the rotor 4 are mounted on its end wall 5.
It is supported in bearings 10 and 11 so as to be rotatable. The rotor 4 and its ends are held together by bolts 48 and nuts 49, for example in a known manner, and slots 47 are provided in the rotor 4 and its end walls 5 as described in the original patent specification. The blades 3 are mounted radially displaceably in the dovetail slots and extend at ends 94, 95 into the end wall of the rotor. A working chamber 17 is formed between the blades, the casing part 7, the rotor 4 and the end wall thereof in a likewise known manner, into which fluid is supplied via a supply conduit 16. Fluid is discharged through the discharge conduit 15, and the fluid flow is likewise directed in the opposite direction in a known manner. The above portions of FIGS. 1 and 2 are known.

What is new in FIGS. 1 and 2 is the construction of the bed 2 with a fluid-tight edge and the wing 3 with a fluid-tight edge supported or arranged so as to be movable therein, as well as the fact that: That is, the fact that there is no need for the conventional end cover on the outside of the end wall 5 of the rotor where the slits 47 are provided, that is, the blade itself
This is because the working chamber 17 is also well fluid-tight even if the outer end closure cover of the rotor is omitted according to the invention. In various embodiments of the invention, however, the outer closure cover of the rotor end wall 5 is also connected to the rotor 4 and to the rotor end wall 5.

In FIG. 1, a bearing 10 is arranged parallel to the axis of the rotor but eccentrically displaced from the coaxial center. According to the invention, a rotating guide ring, i.e. a blade guide 9, is arranged in the bearing 10 and is provided with means for radially guiding the blades 3. In the embodiment according to FIG. 1, the guide of the blades in the rotating guide ring 9 consists of an annular groove 91 with a guide 89 for guiding the inner guide surface into the guide 19 of the blades. Further, a guide surface 86 for guiding the outer guide surface of the blade guide 19 to the guide ring 9.
There is. The wing guides 19 at both ends of the wing 3 engage in a rotating guide ring 9 on the other side of the end wall of the rotor, and the wing guide 19 is thereby forced into the appropriate guide surface 87 or 86 or both guide rings 9 or It is supported on top of that. Said guides are arranged in such a way that the blades 3 always maintain a substantially equal distance from the inner surface 82 of the casing part 7 surrounding the tolerance area and the working chamber. The eccentricity of the support position of the bearing 10 is appropriately determined. However, the configuration of the guide means 9 and 19 is shown by way of example only. The radial blade guidance can optionally be configured differently, provided that the blades 3 are almost always maintained at an equal distance from the inner surface of the casing part 7 within certain deviation limits.

The mutually opposite surfaces of the end walls of the rotor encircle a part of the casing part 7, rendering it fluid-tight when rotating thereon. The bearings and adapters of the rotor, the casing part 7 and the rotor 4, the end wall 5, the casing part 7 in the casing 8 and the shaft 12 are suitably constructed. When the rotor rotates, a working chamber 17 is formed between the rotor 4, the end wall 5, the casing part 7, and the blade 3, and fluid is accommodated in the working chamber through one of the grooves 15, 16 and the other groove. While fluid is discharged through it, the volume of the working chamber 17 increases or decreases when the rotor rotates due to the eccentric arrangement of the aforementioned vane guides, together with the shape of the casing part 7. In this case, the blade guide 19 and the guide means 9, 91, 86, 87 move the casing part 7
, the inner wall 82 and the outer corner of the blade 3 to avoid contact and friction. Due to this, the outer corner of the wing 3 and the inner wall 8 of the casing part 7
The rotor can rotate at a high speed without causing high friction between the rotor and the rotor. However, due to the above arrangement, a gap is formed on the other hand between the outer corner of the blade 3 and the inner surface 82 of the casing part 7, through which the fluid can flow under pressure on one side. from either the wing chamber or the working chamber 17 into an adjacent working chamber. That is, the machine is not easily fluid-tight and cannot be pressurized.

Therefore, in the present invention, a bed 2 with a fluid-tight edge is provided in the wing 3.
A radially movable fluid-tight edge 1 is arranged in the same bed, which absorbs the centrifugal force or, as the case may be, the pressure of the fluid in the bed 2 of the fluid-tight edge. is pressed against the inner wall 82 of the casing part 7. This in itself seems natural, but the arrangement of a radially movable fluid-tight edge into the floor of the fluid-tight edge in the wing does not, however, cause the working chamber 17 through which the fluid flows to be exposed to high pressures. is not sufficient to actually be fluid tight. In the present invention, rather,
It is necessary that the floor of the fluid-tight edge in the blade 3 extends into the blade tip, which itself engages into a slit in the end wall 5 of the rotor. Furthermore, in accordance with the invention, each of the fluid-tight edges 1 extends beyond the entire length of its own rotor 4 and casing section 7, with said fluid-tight edges 1 extending into the blade tips 94, 95. It projects into the fluid-tight edge bearing 2 and must therefore extend over the length of the rotor 4 and the casing part 7 into the end wall 5 of the rotor. Furthermore, the blades 3 have a radius of the blades known from the originally mentioned patent specification of the present inventor, in order that their mutually opposite inner surfaces can slide in a fluid-tight manner on the surface of the casing part 7. A directional extension must be provided at the wing tips 94,95. In order to improve the possibility of producing these mutually facing inner surfaces, a notch 55 is provided between the wing means part and the blade tips 94, 95, for this purpose. This allows the inner surfaces of the wing tips 94, 95 to slide completely in the radial extension of the wing tips 94,95.

The blades 3, 23, 33, 43, 53, 54 are furthermore provided with supply conduits, for example holes 57, through which the fluid-tight edge bed according to the invention is connected to the working chamber 17. For this reason, the pressure of the fluid is increased in the working chamber 17.
into the bed 2 of the fluid-tight edge in the airfoil 3 and the fluid-tight edge 1 radially outwardly into the interior 8 of the casing part 7.
Press 2. On the other hand, the pressure of the fluid coming from the working chamber 7 presses the fluid-tight edge 1 against the fluid-tight floor, the bearing wall or the wall 92 of the floor 2 of the fluid-tight edge, so that the fluid-tight edge 1 form a fluid-tight seal with the inner surface 82 of the casing part 7 and at the same time with the blade tips 94,9.
By forming a fluid tightness inside the working chamber 17 with a bed 2 of fluid tight edges, complete fluid tightness in the tangential direction of the working chamber 17 is obtained. This is particularly clearly shown in FIGS. 19 and 20. The fluid-tight edge 1 has a bearing surface 83 for being supported in the floor 2 of the fluid-tight edge.
and the outer surface 89 form a direct and entirely straight corner 88, which itself also forms a fluid-tight edge floor wall 92 inside the inner surface 82 of the casing part 7 and the tips 94, 95. are in contact with each other. Due to this, the wing tip 9
4 to the middle of the other wing tip 95 and the casing section 7
Complete fluid tightness was achieved along the inner surface 82 of the . Without this configuration according to the invention, complete fluid-tightness is not possible, i.e., otherwise pressure fluid would flow from one working chamber 17 between the blade, the casing part 7 and the end closure 5 of the chamber. through the corners into other working chambers, reducing the fluid tightness and volumetric efficiency of the machine. Other configurations of the fluid-tight edge 1 are shown in FIGS. 4 and 7. The embodiment according to FIGS. 19 and 20 is thus not the only possibility that is suitable for the purpose. When adjacent working chambers 17 form chambers with a fluid-tight edge bed 2 that hold a common fluid and maintain approximately equal fluid pressures, the blade tips 94, 95
It is necessary to close the fluid-tight edge bed 2 in the axially and radially outwardly, for example by means of the outer inner chain part 27 and the axial closing part 18. In this case the outer closing part 29 is the wing tip 94,9
It forms part of a radial wing extension 6 of 5, which part is arranged to slide in a fluid-tight manner on the end wall of the casing part by means of mutually opposed inner surfaces.

FIG. 3 shows an embodiment of the construction of a wing according to the present invention. The fluid-tight edge according to FIG. 4 is inserted into the bed 22 of the fluid-tight edge of the wing 23 according to FIG. 3 and moves radially therein. Wing 23 according to Fig. 3
has no outward closure in the radial extension of the blade tips 94,95. This is because the blade is intended for machines in which fluids and fluids under pressure do not enter the interior of the casing or the slot 47 into the longitudinal floor 2 of the blade. This is particularly the case if the slots 47 are not covered at the axially outer end of the end wall of the rotor by means of an outer cover plate, or if the slots 47, together with other chambers, contain a fluid or a fluid under pressure. This occurs when a common chamber is formed that is filled with The fluid under pressure leaves the slot 47 from the axial end of the blade in this case and enters the longitudinal bed 2 of the blade, pushing the fluid-tight edge radially outwards to the inner surface of the casing part 7. 82
to press. It is advantageous if the fluid-tight edge according to FIG. 4 or in this case its bearing surface 83 is pressed fluid-tight between the walls of the floor 2 of the fluid-tight edge of the wing according to FIG. 3. In the blade 3 according to FIG. 3, particularly good fluid tightness is obtained if the fluid-tight edge 1 is replaced by a fluid-tight edge 41 according to FIG. This fluid-tight edge 41
has radial projections 44, 45 at its ends;
The projection partially surrounds the end of the casing part 7 and slides therein in a fluid-tight manner. The working chamber 17 can be fluid-tight if the blade 3 according to FIG. 3 is provided with a fluid-tight edge 41, as shown in FIG. A rim 41 is used with radial projections 44, 45 at its ends so that the fluid-tight rim bed 2 is connected to a slit 47 or to another chamber containing fluid or fluid under pressure. Even when they are in communication, they are fluid-tight. In this case, the outer corner or surface 81 of the fluid-tight edge 1 according to FIG. .

In the embodiment of the blade 3 according to FIG. 5, the blade 3 has at its ends 94, 95 an outer closing portion 27 for radially closing the bed 2 of the fluid-tight edge in the blade tips 94, 95.
is provided, which extends in the axial direction and forms a guide 19 for the wing. The intermediate piece of the airfoil and the airfoil tips 94,9 can be completely provided with mutually opposing inner surfaces on the radial projections of the airfoil tips 94,95.
A notch 55 (intersecting groove) is formed between the radial protruding portion of 5 and the notch 55 (intersecting groove). You can enter.

In the embodiment shown in FIG. 6, a standard airfoil is shown, which is the type of airfoil most commonly used, which also includes a bed 2 of fluid-tight edges in the tips 94, 95 in a radial direction. An outer closure part 27 is provided for closure. The cross-section of FIG. 6 shows an embodiment of the fluid-tight edge, for example inserted into the floor of the fluid-tight edge of the wing 3, protruding into the wing tip and covering at least two of the notches 55. . This configuration is very important. That is, unless the fluid-tight edge 1 covers the two notches 55 and the ends of the fluid-tight edge 96 protrude into the blade tips 94 and 95, the machine will not be completely fluid-tight. , the reason being that leakage from the working chamber 17 into the adjacent working seal would otherwise be avoided as in the prior art at the end of the fluid tight edge.
the tip 94 of the fluid-tight edge 1 by the end 96 of the fluid-tight edge;
The extension into 95 and the covering of two of the four notches 55 in the corners of the wing by the fluid-tight edges 1 are therefore substantial and important features of the invention. This feature is thus very important and decisive for making the working chamber 17 completely fluid-tight.

In the embodiment according to FIG. 7, the same wing as that according to FIG. 6 is shown. However, at the end of the bed 42 of the fluid-tight edge of the wing 43 according to FIG.
A closing part 18 is arranged inside the 4,95. The closure portion renders the fluid-tight edge floor 42 fluid-tight axially outwardly. The part is therefore made of an elastic plastic material. Since this part is supported on the wing guide 9 as shown in FIG. 1, no axial fixing means are required in the wing 43 either. In the absence of means for supporting the closure part 18, it is fixed within the wing tips 94,95.

Of particular importance is the fluid-tight edge 41 arranged in the wing 43 according to FIG. The same edge has that edge 9
6, a radial protrusion 4 inside the wing tips 94, 95;
4 and 45 are provided, which projections with their mutually opposite inner surfaces abut or slide in a fluid-tight manner on the end faces of the casing part 7. The outer surface 81 and the mutually opposing inner surfaces 90 of the fluid-tight edges 41 therefore surround the inner surface 82 of the casing part 7 and a part of the end face of the casing part 7 and thus ensure a complete fluid-tightness of the working chamber 17. is obtained.
The fluid-tight edge 41 according to FIG. 7 is therefore suitable for integration into the airfoil 3 according to FIG. fluid tight edge 41
It was not previously possible to provide sharp right-angled corners in the wing, however, the installation of fluid-tight edges 41 is now easily possible. That is, the small fluid-tight edges are pressed, sintered or precision cast, for example, from powdered metal or other materials. The fluid-tight rim according to FIGS. 19 and 20 is also suitable for integration into the wing 43 according to FIG. 7. 7 is closed, so that the fluid-tight edge bed 42 forms a common chamber 177 with the adjacent working chamber 17 which is made fluid-tight. . In the cross-sectional view of FIG.
The embodiment is shown in which it is introduced into the floor 2, 42 or 52 of the fluid-tight edge and guided below the fluid-tight edge 1.

The cross-sectional view of FIG.
54 is shown. That is, the wings 53 and 54 are particularly easy to manufacture. That is, the same wing has partial wings 53 and 54.
The fluid-tight edges 52 arranged in one or both of the blades 53 and 54 are made from a material with a modified cross-section, for example rolled or drawn material. The fluid-tight edge floor wall 92 is also fabricated from profiled material true to shape, so that the outer closure, wing floor,
The floor of the fluid-tight edge, the walls of the same floor and the longitudinal surfaces of the blades also require no further machining. The wing parts 53, 54 are assembled to their own wing 3, for example by screwing, riveting, gluing, spot welding or the like. Furthermore, in Figure 8,
The possibility of providing a connecting conduit for supplying fluid to the fluid tight edge 52 is shown. FIG. 2 shows how each connecting conduit 57 connects an adjacent working chamber 17 with the floor 2 of the fluid-tight edge and directs the pressure of the fluid from the working chamber 17 below the fluid-tight edge 1,41. . In order to be able to better manufacture the mutually opposing inner surfaces of the divided wings 53, 54, cutouts 55 are provided at least in the corners of the wings.

FIG. 9 shows the arrangement of the wing guide carrier 39 on the wing 33. A rolling or sliding wing guide 68, 268 or 168 is placed on the carrier. The guide is guided in a suitable wing guide ring.
FIGS. 10 and 11 show a conventional embodiment of the arrangement of sliding wing guide shoes 168, 268, while rolling wing guide means 68 are shown above the wing 33 in FIG. is shown incorporated. In practice, depending on the most suitable configuration of the blade sliding shoe, a configuration not shown in the drawings may also be used.

FIG. 5 shows the inner surface 8 of the wing 3 and the casing part 7.
A cross-section of yet another embodiment of the configuration of Figure 2 is shown. In FIG. 2, one fluid-tight floor is in each case connected to one working chamber 17. That is, the working chamber 17 only needs to be made fluid-tight in the tangential direction, since the other direction of the working chamber 17 with the high pressure depends on the fit, i.e. on the outer surface of the rotor 4 and on the part of the casing part 7. In the embodiment according to FIG. 12, the outer surface 144 of the rotor 4 and the inner surface 82 of the casing part 7 are There is no fluid-tight contact between them. Therefore, in the first part, a cross-section of a part of such a machine is shown.
In the embodiment of the wing machine according to FIG. 2, it is necessary to make the working chamber 17 fluid-tight with the blades 3 in both directions, and on the other hand also to make the respective blade 3 fluid-tight in both tangential directions.

The foregoing provides that, in the present invention, two or Several fluid-tight edge floors 2 are arranged, each of which incorporates at least one fluid-tight edge 1, each of the fluid-tight edge floors adjacent to one working chamber being fluid-tight. This is achieved by connecting a communication conduit 57 from the edge floor 2 to the adjacent working chamber 17. Of particular interest is the configuration of at least two beds 2 of the fluid-tight edge in the wing 3 with a fluid-tight edge 1 therein and the arrangement of the fluid-tight edge with its respective adjacent working chamber 17 by means of a connecting conduit 57. This is the connection of floor 2.

Accordingly, in the present invention, the working chamber 17 having adjacent vanes in the floor 2 with a fluid-tight edge adjacent to the working chamber 17 has two walls bounding the working chamber 17 and the chamber 17. A pressure chamber 177 is formed by two beds of fluid-tight edges in two different blades 2. The pressure of the fluid in this common pressure chamber 177 forces the fluid-tight edge 1 in the bed 2 of the fluid-tight edge radially outwardly against the inner surface 82 of the casing part 7 . A common pressure chamber 177 is made fluid tight. That is, each working chamber 17 forms a common fluid pressure chamber 177 with two adjacent fluid-tight edge beds 2 in two different wings 3 adjacent to the chamber 177 . 4, 7 or 19, 2 into the floor 2 of the fluid-tight edge of the wing 3 of this configuration according to FIG.
Any of the fluid tight edge configurations according to Figure 0 may be incorporated. If special fluid-tightness is required, however, it can be obtained by the design of the fluid-tight edges according to FIGS. When incorporating the fluid-tight edge according to FIG. It should be kept in mind.
The fluid tightness of the working chamber 17, which together with the adjacent fluid-tight bed 2 forms the respective fluid pressure chamber 177, is in this case practically absolute. Neither fluid nor gas escapes from the fluid pressure chamber 17 when the arrangement according to the invention is implemented and technically perfected. Two fluid-tight edges, intermediate pieces at the two corners of the wing and casing part 7
It is often advantageous to introduce a lubricant or a fluid-tight fluid, such as oil, into the chamber between the portions of the inner surface 82 of. This is actually done by the slit chamber 47,
A wing 3 is supported in the same chamber, and for this purpose, from said chamber between the wing, the casing part 7 and the fluid-tight edge 1, passing through the wing 3 or its ends 94, 95, the said slit is inserted. A connecting conduit leading to the chamber is installed as shown by way of example in FIGS. 17 and 18.

The sectional view according to FIGS. 13 and 16 shows an embodiment of a wing 3 having a floor 2 with a fluid-tight edge therein and a connecting conduit 57 leading to an adjacent working chamber 17 arranged in the same floor 2. shows. In order that the inner surface 45 can be made completely, cutouts 55 are likewise provided at the corners of the wing, which corners are each covered by two fluid-tight edges 1 in the floor 2. Wing tips 94, 9 which also have a radial extension 6 into the edge of the bed 2 of the fluid-tight edge
5, if desired or necessary, a closed part 1
8 is inserted.

The cross-sectional views of FIGS. 14 and 17 show the fluid-tight edge 1.
A complete wing 3 is shown inserted into which the fluid-tight edge floor 2 is closed at the ends and radially outwardly in the wing extensions 94, 95.
It is closed due to 7. The above figure shows how the fluid-tight edges 1 likewise cover two recesses 55 in each case so that the inner surface 45 of the radial extension 6 of the wing is completely visible.

15 and 18 show the wing according to FIGS. 14 and 17, which consists of three parts, in this case the wing consists of parts 53, 303 and 5.
4, the same parts being assembled together in the machine but connected together, correspond to the wing 3 according to FIGS. 14 and 17. However, in some applications, the joining of the segmented blades according to FIGS. It is also possible.

Although the present invention has been described above with reference to examples, which are not limited only to the examples, modifications or other configurations can only be made based on the gist of the invention if the range of rotational speeds used is such that the desired effect can be achieved. Rise.

The invention is useful not only in hydraulic pumps and motors, but also in compressors, air or gas motors, and internal combustion machines. Moreover, thanks to the invention, in many applications the rotating casing part 7 can be omitted and replaced by a simple stationary casing part 7, which particularly saves the bearing costs of the rotating casing part 7. Machines constructed in accordance with the invention are therefore not only fluid-tight over large rotational speed ranges, but are often cheaper and even lighter than machines with conventional blade construction.
